     CONSTITUTION: The Y 1 Ba 2 Cu 3 O y  compound (123) placed on Y 2 BaCuO 5  compound (211) is partially molten to produce a liquid phase of BaCuO 2 /CuO which flows down into the Y 2 BaCuO 5  plate 211. Then a peritectic reaction of the liquid phase flowed down from the compound 123 is caused to the plate 211 to form a Y 1 Ba 2 Cu 3 O y  phase (123). The resulting Y 1 Ba 2 Cu 3 O y  phase is cooled slowly in an oxygen-containing atmosphere to produce a superconducting phase. According to this process, crystal particles are uniformly oriented and weak-links among the particles are reduced, and the 211 particles are finnely distributed. As a result, the critical current density of ≥10 4 A is obtained.

Abstract: PROBLEM TO BE SOLVED: To restrain both a reduction of a discharge energy of a spark plug and an LC resonance itself. SOLUTION: When an igniter 13 is turned ON by an ignition timing control part 14 and a primary coil 111 of an igniter 11 is in an energizing state, the ignition timing control part 14 cuts a connection between the primary coil 111 and an LC resonance absorption resistance 32 while the ignition timing control part 14 turns off a FET 31 to thereby prevent a current flowing in the primary coil 111 from decreasing. After predetermined time has passed since the igniter 13 is turned OFF by the ignition timing control part 14 and discharge of a secondary coil 112 starts, the ignition timing control part 14 turns on the FET 31, connects the primary coil 111 with the LC resonance absorption resistance 32 to absorb the LC resonance after discharge of the secondary coil.
